我可以为每个要调用的函数获取函数ID并与之通信吗？

I will call a function to build a BOSH connection using go functionABC().

In the function, I will keep the status of the connection by sending ping information. So, there may be a lot of functionABC() calls. So now, if I want to get some information from the function, can I have some way to identify the function by function ID or process ID? Does Go have function ID's or process ID's to identify a function?

If so, how can I communicate with this function? If not, does there exist any alternative way to accomplish it?

Maybe use a map and return a unique id/connection from your function and assign it to the map, something like this:

var counter uint64

func ReturnStuff() (uint64, net.Conn) {
    return atomic.AddUint64(&counter, 1), nil
}

var m = map[uint64]net.Conn{}

func main() {
    for i := 0; i < 10; i++ {
        id, conn := ReturnStuff()
        m[id] = conn
    }
    fmt.Printf("%+v", m)
}
